Turning off the server
When you turn off the server and leave it connected to ac power, the server can
respond to remote requests to turn on the server. While the server remains
connected to ac power, one or more fans (some models) might continue to run. To
remove all power from the server, you must disconnect it from the power source.
Some operating systems require an orderly shutdown before you turn off the server.
See your operating-system documentation for information about shutting down the
operating system.

from the device, ensure that all power cords are disconnected from the power
